Description

provided by AmphibiaWeb articles
A small, long, very slender, green, savanna-living Hyperolius (19-24 mm) from southern Africa, very similar to H. nasutus. Males the same size as females. Pupil horizontal. The species differs slightly from H. nasutus, but preserved specimens cannot always be distinguished. The main difference is the voice which is a short rattle in H. benguellensis as different from a brief, high-pitched scream in H. nasutus. Some benguellensis has light paravertebral lines, unknown in nasutus. H. benguellensis is normally darker and less webbed than H. nasutus from the same areas, and has, seen from above, a more square snout since the nares are more protruding.The two species have been taken from localities very close to each other, but not on the same breeding localities.

Distribution and Habitat

provided by AmphibiaWeb articles
The distribution is uncertain due to this species' great similarity to Hyperolius nasutus. H. benguellensis has been recorded from southern R.D.Congo, Angola, Zambia, Zimbabwe and Botswana, but the distribution should be taken with reservation due to confusion with H. nasutus.The present account is based on specimens collected in north-western Zambia (Schiøtz and Van Daele 2003)

Hyperolius benguellensis

provided by wikipedia EN

Hyperolius benguellensis (common name: Benguella long reed frog, Benguella reed frog, Bocage's sharp-nosed reed frog) is a species of frog in the family Hyperoliidae. It is found in southern Angola and northern Botswana and Namibia,[2][3] but other sources cite a wider and more eastern distribution.[1] It is similar to Hyperolius nasutus and have been considered a synonym of that species.[2] Hyperolius benguellensis is not considered threatened.[1]

Description

Male Hyperolius benguellensis grow to a snout–vent length of about 19 mm (0.75 in) and females to about 24 mm (0.94 in). Their body is long and slender. Tadpoles are unknown.[3]

Habitat and behaviour

Hyperolius benguellensis is a common frog associated with moist habitats with emergent vegetation (margins of swamps, rivers and lakes) in savanna and grassland habitats.[1] Male frogs call from elevated positions in vegetation. The call is a brief note consisting of five pulses, followed by 14 pulses at a slower rate.[3]
